tJDBCSP – Docs for ESB 6.x

tJDBCSP

Centralizes multiple or complex queries in a database in order to call them
easily.

tJDBCSP Standard properties

These properties are used to configure tJDBCSP running in the Standard Job framework.

The Standard
tJDBCSP component belongs to the Databases family.

The component in this framework is generally available.

Basic settings

JDBC URL

Type in the database location path

Driver JAR

Click the plus button under the table to add lines of the count of
your need for the purpose of loading several JARs. Then on each
line, click the three dot button to open the [Select Module] wizard from which you can select a
driver JAR of your interest for each line.

Class Name

Type in the Class name to be pointed to in the driver.

Username and
Password

DB user authentication data.

To enter the password, click the […] button next to the
password field, and then in the pop-up dialog box enter the password between double quotes
and click OK to save the settings.

Schema and Edit
Schema

In SP principle, the schema is an input parameter.

A schema is a row description. It defines the number of fields (columns) to
be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository.

 

Built-in: The schema is created
and stored locally for this component only. Related topic: see

Talend Studio User
Guide
.

 

Repository: The schema already
exists and is stored in the Repository, hence can be reused. Related
topic: see
Talend Studio User
Guide
.

 

Click Edit schema to make changes to the schema.
If the current schema is of the Repository type, three
options are available:

  • View schema: choose this option to view the
    schema only.

  • Change to built-in property: choose this
    option to change the schema to Built-in for
    local changes.

  • Update repository connection: choose this
    option to change the schema stored in the repository and decide whether to propagate
    the changes to all the Jobs upon completion. If you just want to propagate the
    changes to the current Job, you can select No
    upon completion and choose this schema metadata again in the [Repository Content] window.

SP Name

Type in the exact name of the Stored Procedure.

Is Function / Return result
in

Select this check box , if a value only is to be returned.

Select on the list the schema column, the value to be returned is
based on.

Parameters

Click the Plus button and select the various Schema Columns that will be required by the
procedures. Note that the SP schema can hold more columns than there
are parameters used in the procedure.

Select the Type of
parameter:

IN: Input parameter

OUT: Output parameter/return
value

IN OUT: Input parameters is to be
returned as value, likely after modification through the procedure
(function).

RECORDSET: Input parameters is to
be returned as a set of values, rather than single value.

Note:

Check Scenario: Inserting data in mother/daughter tables, if you want to analyze a set
of records from a database table or DB query and return single
records.

Specify a data source alias

Select this check box and specify the alias of a data source created on the
Talend Runtime
side to use the shared connection pool defined in the
data source configuration. This option works only when you deploy and run your Job in

Talend Runtime
. For a related use case, see Scenario: Deploying your Job on Talend Runtime to retrieve data from a MySQL database.

If you use the component’s own DB configuration, your data source connection will be
closed at the end of the component. To prevent this from happening, use a shared DB
connection with the data source alias specified.

This check box is not available when the Use an existing
connection
check box is selected.

Advanced settings

tStatCatcher Statistics

Select this check box to collect log data at the component
level.

Usage

Usage rule

This component is used as intermediary component. It can be used
as start component but only input parameters are thus allowed.

Dynamic settings

Click the [+] button to add a
row in the table and fill the Code field
with a context variable to choose your database connection dynamically from
multiple connections planned in your Job. This feature is useful when you
need to access database tables having the same data structure but in
different databases, especially when you are working in an environment where
you cannot change your Job settings, for example, when your Job has to be
deployed and executed independent of
Talend Studio
.

The Dynamic settings table is
available only when the Use an existing
connection
check box is selected in the Basic settings view. Once a dynamic parameter is
defined, the Component List box in the
Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario: Reading data from databases through context-based dynamic connections and Scenario: Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
settings
and context variables, see
Talend Studio User Guide
.

Limitation

The Stored Procedures syntax should match the Database syntax.

Related scenario

For related scenarios, see:

Check as well Scenario: Inserting data in mother/daughter tables if you want to analyze a set of records from a database table or DB query and return
single records.
